Observing a catalyst at work: The first 13C cross-polarization (CP)/magic-angle spinning (MAS) NMR spectroscopic evidence for the existence of surface ethoxy species on acidic zeolite Y is reported. In situ 13C CP/MAS NMR–UV/Vis spectroscopy was used to investigate the further decomposition of surface ethoxy species on zeolite H-Y (see picture) to hydrocarbons at elevated reaction temperatures.
